1.5-Inch Deep Gallery Stretcher Bars (Pre-Squared) — The Exhibition Gallery Wrap Standard
Engineered for modern unframed Gallery Wrap presentations and contemporary Canvas Floater Frames, our 1.5-inch deep pre-squared armatures are milled from finger-jointed, kiln-dried North American pine with a raised perimeter bead that prevents bar "ghost lines" on your painting.
The Collector's Story: Why Professional Painters Reject Fixed "Strainer" Bars
Every canvas painting is a dynamic mechanical system under high physical tension. Cheap art-supply store bars are milled from green, unseasoned softwood that twists ("propellers") as Long Island and New York seasons shift from humid summers to heated winters.
At our Farmingdale, NY manufacturing facility, our 1.5-Inch Deep Pre-Squared Gallery Stretcher Bars are built from kiln-dried, finger-jointed pine with zero knots or sap pockets. Designed to pass our studio's acoustic "Drum Test," the 1.5-inch architectural profile gives your canvas a commanding three-dimensional edge on the wall—whether hung unframed as a modern Gallery Wrap or suspended inside a Canvas Floater Frame.

Choosing between 1.5-inch and 1.0-inch depth depends on how you plan to frame or display your stretched canvas:
1. 1.5-Inch Deep Gallery Wrap Bar
Bold 1.5" side profile engineered for frameless modern Gallery Wraps (stapled on the back) and deep Canvas Floater Frames.
2. 1.0-Inch Deep Standard Gallery Bar
Tailored 1.0" depth engineered to drop cleanly inside the rabbet of our Plein Aire, Ornate, and Traditional Picture Frames.
3. Professional Canvas Stretching

Mechanical Engineering & Canvas Bleed Specifications
What separates a true museum stretcher bar from flat hardware lumber? A precision-milled raised outer bead along the front edge of the bar.
- Zero Wood-to-Paint Contact: The raised outer lip suspends the stretched canvas in mid-air so only the very outer perimeter touches wood. When your palette knife or brush presses against the canvas, it never hits the inner edge of the wood bar—completely preventing unsightly rectangular "ghost lines" from appearing on the face of your painting.

To wrap your canvas around the 1.5-inch sides and staple it cleanly to the rear of the bar using hospital corners, use the Abbot Art Bleed Formula from our Professional Canvas Stretching Guide:
- Formula:
Bar Depth (1.5") + 0.5" Rear Staple Margin = 2.0" Bleed Per Side. - Total Extra Canvas Needed: Add 4.0 inches total to both the height and width of your target stretcher bar size (e.g., a 24"x36" bar requires a 28"x40" unstretched canvas sheet).
While a 1.5-inch Gallery Wrap can hang frameless, galleries and collectors frequently elevate 1.5" canvases using an L-profile Canvas Floater Frame:
- The Hovering Shadow Gap: A floater frame screws into the rear of the 1.5" stretcher bar, leaving a 1/8" to 1/4" dark "reveal" gap around the perimeter so the painting appears to levitate inside the frame with zero front lip covering your edges.
